Are you looking for maximized productivity without compromizing safety? Is compliance with global and local standards and regulations together with swift project execution important to you? That s where ABB can help you. Our extensive experience working with explosive atmospheres along with our comprehensive motor and drive testing ensure that the components are combined in the optimal way to cope with the circumstances on site. Our wide global support network and extensive range of services ensure that your motor and drive packages keep running reliably with top performance throughout their life cycle. You ll have the full advantage of accurate motor speed control without compromising on safety or reliability. The benefits of purchasing a motor and a drive together from ABB for applications in potentially explosive atmospheres Cost and time savings as no project-specific testing and certification of the motor and drive combination is needed. Cost savings due to optimized performance of the motor and the drive package; there is no need to oversize the motor. Selecting the right motor and drive is very easy with our software tools and instructions. Tested motor and drive combinations make thermistor protection optional and save on installation costs.

7 ABB LOW VOLTAGE MOTORS AND DRIVES FOR APPLICATIONS IN EXPLOSIVE ATMOSPHERES 7 Typical applications A potentially explosive area is defined as a location in which gases, vapors, mist or dust mixed with air may form a flammable mixture. These areas can be found in, for example, a sawmill where sawdust has been allowed to gather in large amounts, in a food factory handling sugar or flour, and in sewage treatment where methane is present. Below is a list of industries, relevant to the respective motor and drive family, where explosive atmospheres often exist. 01 Oil and gas 02 Chemical industry 03 Mining 04 Water treatment 05 Food and beverage 06 Sawmills 07 Pharmaceutical 08 Textile industry 09 Marine 10 Power generation Correct dimensioning is important We help you to size motors and drives to your exact needs. Correctly sized motors and drives reduce motor frame heating and sparking from bearing currents. They also help you to reduce your energy use. We have the certificates We have our own test center where we can test and certify motor and drive combinations. Our low voltage motors for explosive atmospheres and low voltage industrial drives have been tested to verify that, when correctly dimensioned, they are always safe to use in explosive atmospheres. Global service and support network Our global network of certified service providers are trained and experienced to help you with motors and drives for applications in explosive atmospheres. Our service ensures that your ABB Declaration of Conformity is retained.
